Heartbroken mum: ‘I’m so sorry l couldn’t save you’
The mother of the little boy killed by his own father in a north Queensland murder-suicide has paid tribute to her "beautiful boy" in a gut-wrenching message.
In a heartbreaking post on social media on Saturday, Natsuko Kurihara pleaded for her son Koah, 4, to forgive her, saying, "I'm so sorry I couldn't save you".
She wrote that Koah was killed by his father Troy Harvey on Friday, in a crime that has shocked the small community of Rossville, south of Cooktown.
"My beautiful boy Koah, he has had only 4 years of life, this has been taken by his father. He then took his own life," Ms Kurihara wrote.
"I'm in pain life is not fair.
"Let the people you love know you love them as they can be taken from you.
"I'm so sorry Koah l couldn't save you. Love you forever."
The bodies of fisherman Troy Harvey, 46, and his four-year-old son Koah were found at their Rossville home on Friday morning.
Police who arrived at the horrifying scene are understood to have worked for up to an hour doing CPR to try to save the boy until paramedics arrived.
Police said the boy's mother was not home at the time.
